ESD clamp for HDMI — what the 0402 footprint buys you
Its 0402 (1006 Metric) / 2-X1SON package keeps the trace stub short, preserving signal integrity at multi-Gbps data rates. The 5.5V reverse standoff voltage covers the HDMI common-mode range, while the 14V clamping at 2.5A (8/20µs) shunts IEC 61000-4-2 level 4 strikes without latching the line driver.
40W peak pulse — how much energy can it take?
Rated at 40W peak pulse power (8/20µs waveform), this diode handles the short-duration energy of an ESD event — not a sustained surge. For HDMI port protection, that is the right spec: the 2.5A peak pulse current covers the typical 8kV contact discharge without exceeding the junction temperature limit. The 6V minimum breakdown voltage gives enough margin above the 5V supply rail to avoid false triggering on normal signal swings.
Industrial temp range — where it goes
The surface-mount 0402 package reflows on standard lead-free profiles; no special bake required if the moisture barrier bag is intact (MSL 1 implied by the small body size).
